Abstract (en)

[origin: EP3974027A1] The purpose of the present invention is to provide a PACAP peptide having improved stability. The present invention is based on the finding that the stability of PACAP is significantly improved by substituting aspartic acid at positions 3 and 8 in the sequence of PACAP with at least one amino acid selected from the group consisting of tetrazole-substituted aspartic acid (Tz), tetrazole-substituted glutamic acid (egTz), tetrazole-substituted homoglutamic acid (nvTz), sulfoxy-substituted aspartic acid (cya), and oxadiazolone-substituted aspartic acid (50xa).
